Why can't a jet stream cause a tornado?
The jet stream produces wind shear, or differences in wind speed and direction with changing height. Wind shear is a necessary ingredient for producing tornadoes, but on its own it can't do much. To get tornadoes you need thunderstorms. When thunderstorms develop in strong enough wind shear they can start to rotate. This rotation can the develop into a tornado. But this sort of rotation cannot be produced by wind shear alone.
Fast moving currents of air found near the top of the troposphere are called?
Jet streams. They are high altitude bands of fast-moving air that flow from west to east in the upper troposphere and lower stratosphere. Jet streams are driven by a combination of temperature gradients, the Earth's rotation, and atmospheric pressure differences.
What are narrow belts of high speed winds?
Jet Streams
Where are the jet streams located?
Jet streams are fast flowing, narrow, meandering air currents in the atmospheres of some planets, including Earth. On Earth, the main jet streams are located near the altitude of the tropopause and are westerly winds (flowing west to east).
What is the area called where jet streams are found where cold and warm air meet?
Jet streams are generally located near the tropopause, the layer between the troposphere (where temperatures decrease with altitude) and the stratosphere (where temperatures increase with altitude).
How many jet streams are there on earth?
There are typically four jet streams on Earth: two in each hemisphere. These are the polar jet streams and the subtropical jet streams. Polar jet streams are found closer to the poles, while subtropical jet streams are located closer to the equator.
What does large temperature gradient at high altitudes of the atmosphere cause?
Polar jet streams
What a large temperature gradient at high altitude of the atmosphere cause?
Polar jet streams
Where are the major jet streams in the ocean?
There are 2 jet streams in the northern hemisphere and 2 in the southern hemisphere. They are known as the subtropical jet stream and the polar jet streams subsequently for get side.

What are high altitude high velocity of air called?
jet streams
What two major jet streams are in the northern hemisphere?
The Polar Jet Stream and the Subtropical Jet Stream are the two strongest jet streams in the Northern Hemisphere. The Southern Hemisphere has two major jet streams like the Northern Hemisphere.
What are all the types of jet streams?
Jet streams are primarily categorized into two types: the polar jet streams and the subtropical jet streams. Polar jet streams occur at higher latitudes, typically between 30° to 60° latitude, and are associated with the boundary between cold polar air and warmer air from the south. Subtropical jet streams are found at lower latitudes, around 20° to 30° latitude, and are linked to the subtropical high-pressure systems. Additionally, there can be smaller-scale jet streams, such as the tropical jet stream, which can influence weather patterns in specific regions.
How do jet streams create local storms?
Jet Streams are fast blowing winds above the troposphere. The blow at speeds of upto 120kmph. When two jet streams collide it causes storms.
Fast moving currents of air found near the top of the troposphere are called?
Jet streams. They are high altitude bands of fast-moving air that flow from west to east in the upper troposphere and lower stratosphere. Jet streams are driven by a combination of temperature gradients, the Earth's rotation, and atmospheric pressure differences.
What are two types of jet streams?
The two main types of jet streams are the polar jet streams and the subtropical jet streams. Polar jet streams are located at higher latitudes and are typically stronger, influencing weather patterns in mid-latitude regions. Subtropical jet streams, found at lower latitudes, occur at higher altitudes and generally have a more consistent flow. Both types play crucial roles in shaping weather systems and influencing climate.
What is the similarity between tornado and jet stream?
Both tornadoes and jet streams are air currents that move rapidly in a specific direction. Both are driven by differences in temperature and pressure in the atmosphere. However, tornadoes are more localized and destructive compared to the larger and more consistent jet streams that flow at high altitudes.
